Abstract

LAS FIBRAS, PREFERIBLEMENTE MICROFIBRAS, DE UN POLIMERO AROMATICO DE VINILO SINDIOTACTICO SE PRODUCEN MEDIANTE UN PROCESO DE SOPLADURA DE LA FUSION EN QUE UN POLIMERO AROMATICO DE VINILO QUE TIENE UN ALTO GRADO DE SINDIOTACTICIDAD SE INTRODUCE DERRETIDO DESDE POR LO MENOS UN ORIFICIO DE UNA BOQUILLA EN UNA CORRIENTE DE GAS QUE ATENUA EL POLIMERO DERRETIDO EN LAS FIBRAS. DICHAS FIBRAS SON ESPECIALMENTE UTILES EN LA PREPARACION DE ESTERAS NO TEJIDAS QUE TIENEN UNA UTILIDAD EN EL CAMPO DE FILTRACION, COAPULACION Y AISLAMIENTO A ALTA TEMPERATURA.FIBERS, PREFERABLY MICROFIBERS, OF A SYNODOTACTIC AROMATIC VINYL POLYMER ARE PRODUCED THROUGH A FUSION BLOWING PROCESS IN WHICH A AROMATIC VINYL POLYMER THAT HAS A HIGH DEGREE OF SYNDIOTACTICITY IS INTRODUCED AT A DETACHED RATE A GAS FLOW THAT ATTENUATES THE MELTED POLYMER IN FIBERS. SUCH FIBERS ARE ESPECIALLY USEFUL IN THE PREPARATION OF NON-WOVEN MATS THAT HAVE A UTILITY IN THE FIELD OF FILTRATION, COAPULATION AND INSULATION AT HIGH TEMPERATURE.
